We offer data & analytics services to aid rapid response to major events, such as disasters and emergencies. In this blog, we showcase our efforts in response to a number of major events in Australia during the summer week of 20-26 January 2021. A range of information products related to a tropical low, [...]
Acknowledgements: This project is made possible thanks to the availability of Himawari-8 satellite imagery from the Japan Meteorological Agency (JMA, link) and its open access provided by AWS (link). Mapping bushfires using Earth observation (EO) imagery has been a very active research and application field. With a strong determination to [...]
The new generation of geostationary meteorological satellites, such as Himawari-8 from the Japan Meteorological Agency (JMA, link), offer much improved capabilities of monitoring large-scale weather events in the atmosphere and phenomena on the Earth's surface. Himawari-8 sensors (Advanced Himawari Imagers - AHIs) are equipped with 16 spectral bands: 3 visible bands at 0.5 [...]
It has been well observed, modelled and reported that bushfire risk is on the rise under a rapidly warming climate. Earth observation, remote sensing and image analysis are among the most important technologies to manage bushfires nowadays - from disaster prevention to preparedness, from hotspots detection to movement monitoring, from response to recovery, [...]
11 April 2020 Strongly motivated by the recent release of more detailed COVID-19 data by the New South Wales (NSW) Government, we have developed a new web app that maps the daily confirmed COVID-19 cases in Sydney and NSW by Postcode and Local Government Area (LGA). Please note that so far the [...]
2 April 2020 Sentinel-2 (with twin satellites Sentinel-2A and Sentinel-2B) is one of the most successful Earth observation missions from the EU Copernicus Programme and ESA. Sentinel-2 satellite imagery features: wide swath (290km) multiple spectral bands (13 bands) high resolution (four visible and near-infrared bands at 10m, six red-edge/shortwave-infrared bands at 20m, and three [...]
11 March 2020 Exactly four years ago, we started blogging what we have been exploring and creating in geospatial big data analytics, cloud computing, property location metrics, hazard and risk modelling, etc. So far, more than 50 blogs have been produced. Here we select and share top 10 blogs from the past [...]
9 December 2019 LiDAR point clouds can represent 3D features very accurately, but due to their large data sizes, point clouds are commonly turned into easy-to-use DEMs at various spatial resolutions (e.g. 1m, 5m or 10m). Such DEMs are increasingly available via government web portals. The vertical accuracy of 1m-resolution Lidar-derived DEMs [...]
9 December 2019 Many of us work with elevation data (e.g. LiDAR point clouds and Digital Elevation Models - DEMs) on a daily basis. Nowadays there are an increasing number of government sources for open elevation data, including high-quality, LiDAR-derived DEMs. As we have recently introduced (link to the previous blog), elevation data [...]
18 September 2019 Google Maps is very popular and easy to use, and many of us would have imagined creating and delivering domain-specific mapping layers in the same or similar way Google Maps does. To realise this, we have recently created and released a set of new, high-resolution tiled web maps (or tile [...]
